4. Snap the transmitter back together.
Remote Vehicle Start
This vehicle may have a remote start
feature. This feature allows you to start the
engine from outside the vehicle. It may also
start the vehicle's heating or air conditioning
systems. See Climate Control Systems 0119.
Laws in some local communities may restrict
the use of remote starters. For example,
some laws may require a person using
remote start to have the vehicle in view
when doing so. Check local regulations for
any requirements on remote starting of
vehicles.
Do not use the remote start feature if the
vehicle is low on fuel. The vehicle may run
out of fuel.
The RKE transmitter range may be less while
the vehicle is running.
Other conditions can affect the performance
of the transmitter, see Remote Keyless Entry
(RKE) System 08.
/:This button will be on the RKE
transmitter if the vehicle has remote start.
To start the engine using the remote start
feature:
1. Aim the RKE transmitter at the vehicle.
2. Press and release
Qon the transmitter.
3. Immediately press and hold
/until the
turn signal lamps flash. If you cannot see
the lamps, press and hold
/for at least
four seconds.
When the engine starts, the parking
lamps will turn on and remain on while
the engine is running. The doors will be
locked.
The engine will continue to run for
10 minutes. After 30 seconds, repeat the
steps if a 10-minute extension is desired.
Remote start can be extended only once.
After entering the vehicle during a remote
start, turn the ignition on to drive the
vehicle.
A maximum of two remote starts or a start
with an extension are allowed between
ignition cycles. If the remote start procedure is used again
before the first 10-minute time frame has
ended, the first 10 minutes will immediately
expire and the second 10-minute time frame
will start.
After the engine has been remote started
two times, or a remote start with an
extension, the ignition must be turned on
and then off before the remote start
procedure can be used again.
To cancel a remote start do any of the
following:
.Aim the RKE transmitter at the vehicle
and press
/until the parking lamps
turn off.
.Turn on the hazard warning flashers.
.Turn the ignition on and then off.
The remote vehicle start feature will not
operate if:
.The key is in the ignition.
.The hood is open.
.The hazard warning flashers are on.
.There is an emission control system
malfunction. See Malfunction Indicator
Lamp (Check Engine Light) 076.
.The engine coolant temperature is
too high.

Manual Mirrors
Adjust the mirrors by moving the mirror up
and down and left and right.
The mirrors can be manually folded
in or out.
On the lower portion of each mirror is an
auxiliary convex mirror. A convex mirror's
surface is curved so you can see more from
the driver seat. The auxiliary convex mirrors
can be adjusted manually by moving the
mirror.
Trailer-Tow Mirrors
Vehicles with towing mirrors can be
adjusted manually for a clear view of the
objects behind you.
On the lower portion of each mirror there is
an auxiliary convex mirror that can be
adjusted manually to provide an extended
field of view.
The mirrors can be manually folded
in or out.
Power Mirrors
If equipped with power mirrors, select each
mirror by turning the knob clockwise for the
passenger side mirror or counterclockwise
for the driver side mirror. The center
position is neutral.Adjust the mirror angle by moving the knob
in the desired direction. The auxiliary convex
mirrors can only be adjusted manually.
Folding Mirrors
Manual Folding Mirrors
The mirrors can be folded inward toward
the vehicle to prevent damage when going
through an automatic car wash. Push the
mirror outward to return it to the original
position.

68 Instruments and Controls
to the zone where you live, the compass
may give false readings. The compass must
be set to the variance zone in which the
vehicle is traveling.
To adjust for compass variance, use the
following procedure:
Compass Variance (Zone) Procedure1. Do not set the compass zone when the vehicle is moving. Only set it when the
vehicle is in P (Park).
Press
Tuntil PRESSVTO CHANGE
COMPASS ZONE displays.
2. Find the vehicle's current location and variance zone number on the map.
Zones 1 through 15 are available. 3. Press
Vto scroll through and select the
appropriate variance zone.
4. Press
3until the vehicle heading, for
example, N for North, is displayed in
the DIC.
5. If calibration is necessary, calibrate the compass. See “Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually calibrated.
Only calibrate the compass in a magnetically
clean and safe location, such as an open
parking lot, where driving the vehicle in
circles is not a danger. It is suggested to
calibrate away from tall buildings, utility
wires, manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the DIC display,
the compass should be calibrated.
If the DIC display does not show a heading,
for example, N for North, or the heading
does not change after making turns, there
may be a strong magnetic field interfering
with the compass. Such interference may be
caused by a magnetic CB or cell phone
antenna mount, a magnetic emergency
light, magnetic note pad holder, or any other magnetic item. Turn off the vehicle,
move the magnetic item, then turn on the
vehicle and calibrate the compass.
To calibrate the compass, use the following
procedure:
Compass Calibration Procedure
1. Before calibrating the compass, make sure the compass zone is set to the
variance zone in which the vehicle is
located. See “Compass Variance (Zone)
Procedure” earlier in this section.
Do not operate any switches such as
window, climate controls, seats, etc.
during the calibration procedure.
2. Press
Tuntil PRESSVTO CALIBRATE
COMPASS displays.
3. Press
Vto start the compass calibration.
4. The DIC will display CALIBRATING: DRIVE IN CIRCLES. Drive the vehicle in tight
circles at less than 8 km/h (5 mph) to
complete the calibration. The DIC will
display CALIBRATION COMPLETE for a few
seconds when the calibration is
complete. The DIC display will then
return to PRESS
VTO CALIBRATE
COMPASS.

Lighting 95
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. If the
vehicle has a voltmeter gauge or a voltage
display on the Driver Information Center
(DIC), you may see the voltage move up or
down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, fog lamps, rear window
defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory
power outlets.EPM works to prevent excessive discharge of
the battery. It does this by balancing the
generator's output and the vehicle's
electrical needs. It can increase engine idle
speed to generate more power, whenever
needed. It can temporarily reduce the power
demands of some accessories.
Normally, these actions occur in steps or
levels, without being noticeable. In rare
cases at the highest levels of corrective
action, this action may be noticeable to the
driver. If so, a Driver Information Center
(DIC) message might be displayed, such as
SERVICE BATTERY CHARGING SYSTEM. If this
messages displays, it is recommended that
the driver reduce the electrical loads as
much as possible.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This helps to
prevent the battery from running down.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
